-Rust 1.54 supports invoking function-like macros inside attributes. One notable use case for this is including documentation from other files into Rust doc comments. For example, if your project's README represents a good documentation comment, you can use `include_str!` to directly incorporate the contents. Previously, various workarounds allowed similar functionality, but from 1.54 this is much more ergonomic.
